APPARATUS FOR CARBONATING AND DISPENSING BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 475,128, dated May 17,1892.

Application filed January 28, 1892. Serial No. 419,590. (No model.)

To all whom, it may concern:

Be it known that I, PETER E. MALMsTRoM, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Apparatus for Carbonating and DispensingBeverages, of which the following is a specification.

This invention relates to an apparatus for carbonating and dispensingbeverages; and it consists in certain novel features set forth in thefollowing specification and claims, and illustrated in the accompanyingdrawings, in which p 7 Figure 1 is a side elevation, partly in section,of the apparatus. Fig. 2 is a section of the valve along 00 w, Figs. 1and 3. Fig. 3 is a section along y y, Fig. 2. Fig. 4 is a section along2 2', Fig. 2.

In the drawings, the letter A indicates a bottle or metallic vessel inwhich liquefied carbonic acid is supplied to the trade. On opening valveB the carbonic acid passes through the tube or connection 0. Theequalizing-valve D and gage E are of any suitable well-knownconstruction. nection O alternately supplies the carbonic. acid to thetube F or tube G as the alternating valves H I are operated. The valvesH I have stems K L extending toward a rotary or oscillating head M,having a raised or operating portion N and a depression or cut-away part0. On swinging or moving the head M by handle P the actuating portion Nstrikes first one stem K and then the other stem L, so that the valves HI alternately open and shut. The valves are shut by suitable springs,and said valves may be of any suitable form; but the construction issuch that one of the valves is always seated, this being renderedpossible by the arrangement of the depression 0 of the oscillating headM relatively to the elevation N thereof, so that whenever the elevationopens a valve the depression permits the other valve to close by theaction of its spring. The tube 0, which connects with the carbonic-acidvessel A, opens into the valve-casing at a point between the two valves,as best shown in Fig. 4, and communicates by suitable passages with thevalvechambers, which latter are closed by suitable plugs or screws Q.The tube or connection The tube or con-' F leads to a vessel R and thetube or connection G to a vessel S. A tube or connection T is also madeto connect said vessels. The vessel R being filled with water and theyes sel F being left empty and the valve I being opened, carbonic acidwill enter vessel S through the connection or tube G. 011 moving thehead M so as to open valve H and allow valve I to close carbonic-acidwill enter vessel R and will force part of the water from vessel Rthrough tube T into vessel S, previously supplied with carbonic acid, asstated. On closiu g valve H and openin valve I the water is partlydriven back again from vessel S through tube or connection T into vesselR. By thus alternating the valves H I a sufficient number of times thewater is thoroughly agitated and impregnated by the carbonic acid.

The vessel S is adapted to be placed into a receiver or marble fountain,such as seen in drugstores and other places, and by surrounding thevessel S with ice or other refrigerant the contents of vessel S are keptcooland can be drawn off through valve or faucet U to be served tocustomers. It found desirable, a valve or blow-off V may be provided forvessel S. The valves 11 I are arranged in a valvecasing W, fromwhichextends the tubes F and G, and a pivot or support X for the oscillatinghead or actuator M. The vessel R may have a filling-opening, closed by aplug or stopper Y, and either the vessel R or S, or both, may havesafety-valves, if desired.

7 It will be observed that in my invention the valve-easing is providedwith a triple-tube connection so constructed and arranged that onebranch tube 0 connects with the carbonicacid vessel A, while the othertwo branch tubes F and G connect, respectively, with two communicatingvessels S and R, whereby liquid, while, exposed to the pressure ofcarbonic acid, is caused to travel back and forth between the twocommunicating vessels. In this respect my in vention differssubstantially and materially from prior apparatus of this type of whichI am aware.

An efficient way of operating the device is as follows: Set the valve Dto a pressure of, say, for example, ten pounds,and then charge thevessel S with carbonic acid, as stated. Then close the valves H I andset the valve D for an increased pressuresay, forexample, twelvepounds-and open the valve leading to tube F, so that the consequentincreased pressure in vessel R will force water through tube T intovessel S against the pressure already existing 'in vessel S. valves H Iand again set valve D to an increased pressure-say, for example,fourteen pounds-and on then allowing the carbonic acid to enter vessel Ssome water will be forced from vessel S through tube T into vessel R inspite of the pressure existing in vesv sel B. By thus graduallyincreasing the pressure of the carbonic acid until the required degreeis reached the proper agitation and carbonating is effected.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a valve-casing hava pair of valves provided withstems,- a tube opening into the valve-chamber at a point between the twovalves and adapted to connect with a carbonic-acid vessel, a pair oftubes leading, respectively,fro m the valvechambers and adapted toconnect with a pair of communicating vessels for the purpose of cansingliquid therein to flow from one to the other, and a movable head mountedon the valve-casing and 'havin g means to alternately open one valve andclose the other, substantially as described.

2. The combination of a valve-casing having a pair of valves providedwith stems, a tube opening into the valve-casing at a point between thetwo valves and adapted to connect with a carbonic-acid vessel, a pair ofThen close the tubes leading, respectively, from the valvechambers andadapted to connect, respectively, with a pair of communicating vesselsfor causing liquid therein to flow from one to the other, and anoscillating head mounted on the valve-casing between the valves andhaving a depressed portion and an elevated portion, so that whenever onevalve is opened by the elevated portion the depressed portion permitsthe other valve to close, substantially as described.

3. The combination of a valve-casing having a pair of valves providedwith stems, a tube opening into the valve-casing at a point between thetwo valves and adapted to connect with a carbonic-acid vessel, anequalizing-valve D, arranged on said tube between the valvecasing andthe carbonic-acid vessel, a pair of tubes leading, respectively, fromthe valve-chambers and adapted to connect with a pair of communicatingvessels for causing liquid therein to How from one to the other,

and an oscillating head mounted on the valvecasing between the valvesand provided with an elevation and a depression, so that whenever theelevation opens one valve the 'depression permits the other valve toclose, substantially as described.

In testimony whereof I have hereuntoset my hand in the presence of twosubscribing witnesses.
